Latest Patents
One of his latest patents is a metering device for the inhalation of a pulverulent substance. This innovative device is activated by a user-induced airstream, allowing for the inhalation of medicinal substances. It features a closure cap, a piston, a mouthpiece, and an annular chamber located upstream of the mouthpiece. The storage chamber holds the substance, which can be accessed when the closure cap is removed. The metering rod is designed to remove the medicinal substance from the storage chamber into an emptying-standby position. In this position, the metering chamber is sealed by the piston, which can be displaced by the airstream into an emptying-release position. In this position, the metering chamber is opened, allowing the substance to be drawn in by the suction airstream.
Another significant patent involves a counting mechanism for a drug delivery device. This mechanism includes a first counting member with an interaction element and a second counting member with engagement elements that interact with the first member. The design ensures that the first counting member can move relative to a separating member, preventing engagement when in a specific position. This innovation enhances the functionality of drug delivery devices, making them more reliable and user-friendly.
